Description

Thresher

The utility model relates to a kind of drum with rasp bars thresher that separation and cleaning device are housed, and is a kind of multifunctional agricultural thresher of realizing grain threshing-separation-cleaning with simple structure

Grain separator is a kind of mature technology; early having both at home and abroad can be with grain threshing; and grain separated from cane and clean; obtain various compound thresher and the combine of cleannes at the grain more than 98%; " CK-3 combine " as the Soviet Union; " the MH-890 combine " of the U.S., homemade " good harvest-1100 types " compound thresher etc.Though these compound threshers can be finished threshing-separations-cleaning simultaneously, their complex structures, bulky, involve great expense inapplicable middle individual farming system.Agricultural research designed " southern 352 types " skeleton symbol thresher in Nanjing is that a kind of single tumbling thresher can only threshing and the big cane of separating part, and the cereal after the threshing also need be spent a large amount of labours further to finish to separate and the grain cleaning.

The purpose of this utility model is that design is a kind of simple in structure, and cost is low, and volume is little, the multifunctional agricultural thresher of energy threshing-separation-cleaning the time easy to use.

Design of the present utility model is a kind of thresher; by the feeding platform; cylinder; the casing motor; fan; slide plate is formed; it is characterized in that the end with the feeding mouth cover plate is connected mutually that is positioned at feeding platform front lower place has been connected the feeding mouth guide plate; the other end has connected the lattice-shaped notch board of the high percent of pass of big cornerite that is rearranged by thicker wire and finer wire of a broach sieve, and pass through belt pulley and the V-Belt Drive of broach sieve top drive the check drum that rotates by cylinder and be installed in the utility model thresher that the wind deflector on the slide plate top of putting out cereal on the one's intention as revealed in what one says fan gas channel of putting out cereal is formed.

The garden arc cornerite of the lattice-shaped notch board of the high percent of pass of big cornerite of the utility model thresher is more than or equal to 150 °; The area alive of concave grate (that is: pass through area) is more than or equal to 70%.
